Limits on the Global Distribution of Horseshoe Crabs (Limulacea): Lessons Learned from Two Lifetimesge-scale environmental parameters that limit their global distribution are .

There is a wide variation in the molting rate among larvae obtained from synchronized inseminated eggs and reared under uniform laboratory conditions.

Reproductive Competition and Sexual Selection in Horseshoe Crabs of sexual dimorphism in body size. The intensity of reproductive competition is correlated with nesting density in ., but this is not the case in the Asian species, which rarely have multi-male groups or highly male-biased operational sex ratios.

Essentially, we have selected the big-picture type of conditions pertinent to considerations of the conservation of the species. Thi
